ABSTRACT:
The knee bolster structure to be mounted on an instrument panel 13 comprises a panel 2 and a stay 3 for supporting the panel 2, while the stay 3 is composed of a stay main body 4 and patch 5 so disposed on the stay main body 4 as to cover the stay main body 4. In a vehicle collision, the stay 3 is deformed starting from notches 8 respectively formed in the stay main body 4 but, during the deformation of the stay 3, the leading end side 11 of a top plate 9 provided in the patch 5 is butted against the bottom surface 6 of the stay main body 4, thereby being able to prevent stresses from being concentrated onto the notches 8. Also, since the wall portions 7 of the stay main body 4 are held by the side walls 10 of the patch 5, they are prevented from being opened outwardly. Due to this structure, the drag of the stay 3 or the knee bolster structure can be stabilized, so that shock energy caused in the vehicle collision can be absorbed efficiently.
